考察了等离子喷涂Ｃｒ３Ｃ２－ＮｉＣｒ涂层及其表面化学镀Ｎｉ镀层通过不同配副组成摩擦副的摩擦学特性，并应用ＳＥＭ、ＸＲＤ和ＸＰＳ对磨痕进行了分析．结果发现：等离子喷涂Ｃｒ３Ｃ２－ＮｉＣｒ涂层及其表面化学镀Ｎｉ镀层自配副组成摩擦副，均表现出较大的摩擦系数和磨损系数；但是，Ｃｒ３Ｃ２－ＮｉＣｒ涂层表面化学镀Ｎｉ镀层与Ｃｒ３Ｃ２－ＮｉＣｒ涂层配副组成摩擦副，在于摩擦条件下，能达到０．１２的摩擦系数和接近１０－６ｍｍ３（Ｎｍ）－１的磨损系数．上述结果是由于Ｃｒ３Ｃ２－ＮｉＣｒ涂层的磨损机理从强烈的层状颗粒剥落转变为沿气孔和微裂纹等处的颗粒断裂．
The tribological properties of plasma sprayed Cr3C2-NiCr coating and electroless Ni plating on the surface were investigated. The wear scar was analyzed by SEM, XRD and XPS. The results show that the plasma spraying Cr3C2-NiCr coating and the surface electroless Ni plating have self-match friction pairs, which all show larger coefficient of friction and wear coefficient. However, the surface of Cr3C2-NiCr coating with electroless Ni plating and Cr3C2 NiCr coating with the deputy composition of the friction pair, under the friction conditions, can reach 0.12 and close to 10-6mm3 (Nm) -1 wear coefficient. The above results are due to the wear mechanism of the Cr3C2-NiCr coating which changes from intense lamellar particle spalling to particle rupture along pores and micro-cracks.
